Uy, para sa ganitong tanong about meds during pregnancy, talaga dapat kang makipag-consult sa OB mo muna, ha, kahit vitamins, kailangan sure na okay lang talaga for baby. I know maraming preggies ang nag-take ng B-complex, pero bawat pregnancy is different, and your doctor knows best what's safe for you specifically. Better safe than sorry, 'di ba? Text or call your OB clinic agad para malaman mo exactly kung pwede or kung may alternative na mas better. Sending you good thoughts, you're doing the right thing by asking!
